Flashed the base tune from Xero-Limit running. Car had trouble starting up. Engine turns over but RPM’s go down to like, 0. Engines dead quiet. I have to give it steady gas for about 10 seconds to keep it alive and it will eventually stay alive but my idle RPMs are around 400-600. My ABS (C1288) and ECM (P0171) codes are on. My oil pressure lamp flickers on faintly and sometimes remain on.

My ABS and Traction Control lights are on as well. None of these lights were on before installing my Supercharger. Car drives fine even though dash is lit like the Vegas strip.



Is this meant to happen due to the base tune or is something seriously messed up with my car?



Besides the SC install (Sprintex 210), I also had a Flex fuel kit installed. My installer used the rear o2 sensor from my catless header with the flex fuel kit.

it's messed up. Probably the tuner doesn't care about doing it right.

I hope that's not the case.. spent $850 on the tune including the ecutek cable and license.



Stock PI, MAP. Not sure about the callibration, I'd assume that is my tuner's job.

The brake pedal feels soooo hard to press down.. Not sure if that's tune related.

If brake pedal is hard to press = incorrectly connected vacuum hose. Check if your brake vacuum hose is connected after throttle body. Then, FA20 engine has two crank ventilation ports, one with pcv valve, should be connected after throttle body to intake manifold as well for high vacuum, and low vacuum ventilation is before the trottle body. If you have it misaligned or wrongly connected you might have vacuum leak somewhere causing you engine is running very lean and fueltrims are maxed.

Thank you sir. Could misaligned hoses also cause the P0171 code?

You have like 10 different threads created over your messed up install. With people just repeating the same things over and over for you to check and fix. It’s essentially just a manifold swap not that many things to check or that could go wrong. If you haven’t resolved this yet then honestly at this point tow it to a reputable shop and have them reinstall/fix it instead of having your friend install it before you do irreversible permanent damage to your car.

Good luck, I hope you get it fixed.

Yeah that's true, but installer's my buddy and I wanted to pay and support my buddy than a shop, but I've learned my lesson.




Yes, I remember, but the SC kit itself has no problems. Just ran into some problems after the installation.
